Specification of Letters Patent.

Patented Apr. 21, 1914.

Application filed May 20, 1913. Serial No. 768,853.

To all whom it may concern.

Be it known that I, Gusravn SANDE, a subject of the King of Sweden, and resident of the city of Seattle, King county, Washington, have invented certain new and useful Improvements in Railway-Rails and Joints Therefor, of which the following is a speci-' fication.

My invention relates to railway rails and joints therefor, and comprises a new form or shape for the rail and a new manner of connecting their ends.

The object of my invention is to produce a type or shape of rail which is especially adapted for use with a type of wheel which consists of a broad surfaced tread and which has no flanges, said wheel being of a type which is used by me upon cars designed for use upon mono-rail systems, the rail being thus intended principally for use with mono-rail systems, although it may be adapted for other special uses.

Another object of my invention is to provide a means for connecting such rails at their joints which will be a material improvement over other and common connecting means.

My invention comprises the novel constructions and parts which will be hereinafter described and particularly pointed out in the claims.

In the accompanying drawings I have shown my invention embodied in the form which is now preferred by me. These drawings are to be understood as illustrative of the principles comprised in my invention and not as limiting it to the proportions and sizes of the parts thereof, as these may be varied as desired or to suit varying conditions which will be encountered.

Figure 1 shows, in perspective, a short section of the meeting ends of two rails and the manner of securing these together. Fig. 2 shows a cross-sectional elevation of the rails and their joint;

This rail has a broad base composed of a relatively thin web A, and two tread, or hearing flanges, B, which extend upwardly from the base web, at points located well toward the side, and yet at such a distance from the side edges as to leave a considerable portion of the bottom web beyond the tread flanges. This provides a supporting base which extends each way from the tread flanges. The rail, as thus made, constitutes a channel bar in which the upwardly extending flanges are greatly thickened and in which the base web is continued beyond the flanges at each side. In connection with such rails, I use a joint forming plan which employs a channel bar C, which is rolled of such size that it will tightly fit between the flanges of the rail. The rail flanges and the flanges of the connecting bar are provided with registering holes for the reception of connecting bolts D, similar to those used for securing the fish-plates of the common type of rail joint.

Outside the tread flanges B, are secured plates or bars E, which may be of the usual or any other approved type and are secured to the rail by the usual bolts, as D.

The upper level of the tread flanges B of the rail, and of the flanges F, of the connecting bar C, should be at the same level, or conform to the wheel tread used, so that the wheel tread will bear upon both when passing over the joint, thus preventing the jar which occurs in passing the joints of rails of the common type of construction. The ends of the connecting bar O, should have the upper flange-edge surfaces inclined slightly, so that there will be no sudden rise caused in case the flange of the connecting bar should be slightly higher than the tread surface of the rail.

The rail may be secured down by spikes or bolts G, which pass through the web between the tread flanges, or by similar spikes or bolts H, which pass through the web outside the tread flanges, or by both, as desired. Where the bolts are employed between the tread flanges, these may also pass through the connecting bars C.

The shape of the tread surface of the wheels which are designed for rolling upon this rail, is shown by the dotted line I, the same being but slightly convexed. This wheel has no flanges engaging the side surfaces of the tread flanges, this function of the usual type of rail and wheel, being performed by other wheels which engage rails placed at the side of the track structure, the same not being here shown, as they form no part of this invention.

The channel formed between the tread flanges may be filled with any suitable material, as wood, cement, asphalt, etc., should,

this be desired. The bottom web of the rail may also be provided with drainage holes for the carrying off of the water.

What I claim as my invention and desire to patent is;

1. A railway rail having a base web and two tread flanges spaced inward from its side edges, and a connecting bar of channel cross-section fitting closely between the tread flanges of the rail and bolted thereto.

2. A railway rail having a base web and two separated tread flanges spaced inward from its side edges, and a connecting bar of a channel cross-section fitting closely between the tread flanges of the rail and bolted thereto, the upper edge surfaces of the flanges of the connecting bar conforming to the tread surfaces of the rail flanges, whereby it forms a tread surface to carry the wheels over the joint.

In testimony whereof I have hereunto affixed my signature this 12th day of May, 1913.

GUS SANDE.
